SPECIFCATION forming part of Letters Fatemi;l No. 337,653, dated March9, 1886.

Application filed December 7, 1885. Seral No. 185,011. (No model.)

To all whom, it may concern.-

Beit known that I, FRANKLIN l?. BnIsEL, a citizen ofthe United States, aresident ofthe town of Pottstown, county of Montgomery, State ofPennsylvania, have invented a new and useful Improvement in Look-Nuts,of which the following is a specification.

rlhis improvement is more particularly re lated to the class oflock-nutsintended for use upon the fish or splicing plates of railroadrail-joints, although adapted for general use as a lock-nut.

The object of the invention is to secure a positivelock for the nut,with anydesred tenx5 sion upon the bolt, so that the fish-plates may bedrawn together with sufficient force to sustain the rail, yet willprovide for a certain amount of sliding play of the rail upon the same,thus permitting expansion and con` 2o traction to take place withoutdisturbing the alignment ofthe rails. It is well knownthat a certainamount of sliding play is desirable at the joint; but in all thelock-nuts with which I am acquainted the nut cannot be adjusted withsut'licient positiveness to retain the rails in sliding contact, theyinvariably becoming loose ina short time after adjustment. This desiredresult I attain by my improved mode of locking the nut, as will be 3omore clearly explained vwhen referring to the drawings herewith, forminga part of this specitication, in which like letters of referenceindicate like parts.

Figure l represents an ordinary fish joint or splice with my improvednut-locking device thereon; Fig. 2, a cross-sectional elevation on theline of one of the splice-bolts; Fig. 3, a detached elevation of thecombined lock-shell and washer, the protector-case 4o shown in section;Fig. 4, a detached elevation of the washer, showing one of the recessedways with its keeper-hook. Fig. 5 represents an exterior end view of thelocking-shellwith aportion of the nut-locking end removed to show thelockinglugs at the inner end of the shell and upon the interior facethereof. Fig. 6 is a vertical section of the l0cking-shell,showing thelocking-lug and nutlocking aperture. 5o In the drawings, A representsthe railroadl rail; B, the tish or splice plates; C, the usual bolts,having an enlarged body at O', to prevent turning, a head, C2, andhexagon or square nut C3. The nut-locking device is composed ofa washer,D, formed with a collar, D', an offset, D2, and bolt-aperture D3. Anannular shell, E, passes freely over the body D of the washer, and theouter end is partially closed by a ring, E', having an aperture, E, cuttherein for either a square or 6o hexagon nut, adapted to the bolt, andsaid aperture is cut slightly larger than the plan of said nut, so as tomove freely over the same. A spiral spring, F, of suitable strength,preferably of brass wire, is adapted to slip over the body D of thewasher, and on screwing up the nut C"s the springF will be compressedbetween the end ot' the annular shell E and the collar D. Diametricallyopposite, upon the body D, and reverse to each other, re- 7o cesses orpassages D* are out down to the level of the offset D2, and of the formshown, or its equivalent, producing a keeper-hook, D5, upon the body oi'the same. Lugs E3 E3 are placed diametrically opposite each other uponthe inner face of the shell E at its inner end. Said lugs E3 aredesigned to project within the shell far enough to just clear the offsetD2 of the washer D, and are made of asuitable size to pass freely intoand around the passages D4 8c and finally lock beneath the keeper-hookD5. A case, G, is stamped out of tin-or light sheetiron, open at thefront, and with an aperture, G', in the rear to pass over the bolt C.The washer D drops freely within the case, which serves to protect thecombined parts from injury, and prevents tampering therewith byunauthorized persons.

To use the device, the fish-plates B and bolts C are placed upon ltherail A. The washer D 9o has the spring F slipped upon the same, andresting upon the collar D. The shell E is then placed with its lugs E3over the offset D-l and within the passages D4. The spring F is thencompressed until the lugs E are brought in line with the horizontalpassage, when the shell is partially turned toward the right, so as tothrow the lugs within the same. This done, the spring is retained in aconlpressed condition, and washer and shell, virroo tually forming oneintegral piece, are placed within the case G and slipped upon the boltC. The nut (Yi is now run down upon the bolt until it contacts with theend of the washer and drawn up tightly. A smart rap ofthe hammer isgiven to the head C of the bolt to insure snug work, andthe shell Eisagain turned forward until the aperture El coincides with the nut 011plan, and the lugs E* will have arrived in line with the inner verticalpassage, when the resilience ofthe spring F will drive the shell Eoutward and the aperture El, sur rounding the sides of the nut c3, willlock the same therein. Aslight relaxation ofthe bolt tension is nowgiven by a reverse turn to the uut, which at the same time lodges thelugs E" under the keeper-hooks D5, and there can be no furtherloosening` ot' the nut without the shell-lugs were shcared ott', whichis not at all likely to occur,nnless intentionally done f'or a maliciouspurpose. To release the nut it is again turned to tighten up the same,which brings the lugs out from under the keeperhooks and in line withthe inner vertical passage. The shell is then shoved inward, againcompressing the spring F,and being turned to the left the lugs arecaught as beiore in the horizontal passage, and the shell is held out ofthe way of the nut until the same is removed, or until it is desired toreplace the same.

It will be apparent that the locking device may be used without thespring, as it' the shell is placed upon the \wasl1er,as descrihed,and atthe proper time, j ust before relaxing` the ten sion ot' the nut uponthe bolt, it is pulled toward the operator and made to coincide with thenut,as before. Then ou relieving thestrain upon the bolt the lugs willbe thrown under the keeper-hooks,and nofurther release ot' the nut cantake place. I prefer, however,to make use of the spring,as the outwardmovement of the shell toward the nut is at the proper ti me automatic,and the parts being held in close Contact thereby there is no noisecreated by loose parts as there would he without the use of the spring.

The washer D and shell E and the case G, if so desired,may all beconstructed of castiron, being adapted to be easily molded and east ofthesame,and little subsequent work upon them will be requisite, afterthe pieces leave the tumblingehurn, to lit them forimmediate applcation.

I am aware of much that has been done in the line of lock-nuts forrailway splices, and believe that Ihave developed a new and novel lock,simple in its construction, positive in its action, and which may berepeatedly placed and removed without injury to the same.

As shown upon the splice, a portion of the 6 washer-collar is flattenedto lie upon the foot of the fish-plate or on the foot ofthe railwhen theusual plain Hat splice-plate is used. 'This prevents the turning of thelocking device while the nutisbeing tightened up or released; 6

but the nut-locking device is applicable to many other purposes, audvarious modes may be adopted to prevent turning-such as pins cast uponthe outer face of the washer and countersunk recesses punched or formedin the 7o rails Yet will not be sufiicient to iroduc-e in- 8O jurionslooseness of' the several parts.

Having shown the eonstructiomuse, and advantages o1" my improvednut-locking device,

I desire to secure by Letters .Patent the following claims upon thesame: 8 l. As an improved nut-locking device, an

annular shell, E,havinglugs E at its inner interiorsnri'ace and in itsouter end an aperture, E, conforming with and adapted to receivethe nutC* ol" the bolt C, in combination 9 with a body-washer, D, with collarD', recesses D, and keeper-hooks D5` adapted by perforation D:i to slipover said holt, and a spring, F, all arranged and adapted to be operatedtogether substantially as shown, de- 9 scribed, and for the purposespecified.

2. In combination with a nut-locking dcvice consisting ot a perforatedbody-\\'aslier, D, with passages D" and keeper-hooks D5, formed upon orwithin the same, and an an nular shell, E, having a nut-aperture, E2,and lugs E, adapted to move within the passages D" and lock beneath thekeepers D, as described, an outer open case, its inner end perforatedfor the bolt G, said case adapted to reeeivethe collar D' of the washerD, and to conceal and protect the spring F and contacting parts ofwasher and shell in the manner as shown,and for the purpose set forth.
